## Usage

Conversations are ChatML `messages` lists. Tool calls are written inline in the
assistant content as MiniCPM5-style XML, so the chat template applies directly:

```python
from datasets import load_dataset
from transformers import AutoTokenizer

ds = load_dataset("koshuro/fable5-chatml", split="train")
tok = AutoTokenizer.from_pretrained("openbmb/MiniCPM5-1B")
text = tok.apply_chat_template(ds[0]["messages"], tokenize=False)
```

Assistant chain-of-thought is wrapped in `<think>…</think>`. Tool results are
`role: "tool"` messages, which the template renders as `<tool_response>`.
